[Bug 429819] [NEW] [Karmic] Right-clicking on a bookmark in Firefox hangs the whole desktop

[Tristan Schmelcher]

Public bug reported:

Binary package hint: firefox-3.5

(Also occurs with firefox-3.0)

Sometimes when I right-click on a bookmark in Firefox's Bookmarks menu,
the browser and the entire desktop hang. I can still move the mouse
pointer, but all input is ignored. I can only recover the system by
switching to a virtual terminal and killing Firefox. I have attached a
symbolicized stack trace of the hang that I took back on Firefox 3.0.

The bug seems to be related to the contents of the clipboard. i.e.,
clipboard content can be "bad" somehow, and if I right-click on a
bookmark with "bad" content in the clipboard then the bug always occurs.
I say this for two reasons:

1) After killing Firefox, I can always make the bug happen again immediately by re-opening Firefox and right-clicking on a bookmark.
2) If I copy new text from somewhere with Ctrl+C and then right-click on a bookmark then the bug does _not_ occur.

I have identified one application that consistently repros the bug if I
copy text from it: Quartus II. Unfortunately though it is not free, so
you'd have to buy it to repro this way. It does not cause any problem
when I copy its text to other apps.

Note that I am technically on Jaunty, but with lots of Karmic packages
installed (including firefox-3.5), so the below output may be confusing.

I am opening this bug against the X server too, because it is a serious
bug in its design for an application to be able to hang the whole
desktop.
